As a coach and fitness writer, having tight hips is one of the most common complaints I hear about. People usually default to stretching to sort this out, but a specialist says there are more effective ways to address the problem.
Movement mechanics expert and Training Stimulus founder Ash Grossmann says regular movement and developing stability around the joint are likely to yield better long-term results for those seeking to banish tightness.
“In terms of broad, generalised advice, we want to establish what is causing the tightness,” Grossmann says. “There are indirect reasons why a muscle could be becoming tight – the clue is if you stretch it and the tightness keeps coming back, stretching isn’t solving the tightness.
“In a lot of situations, stretching can actually make it feel worse because you get into a wrestling match with your nervous system. Your nervous system generally has your best interests at heart with the tools it has available, so it thinks it’s doing you a favour by tightening the muscle. Yanking on that tight muscle [via stretching] can be hurting your bigger picture goal rather than the small muscle tightness you’re dealing with.”
Below, Grossmann explains the possible causes of muscle tightness, and an accessible protocol for combatting this around the hips.

Possible causes of muscle tightness
Protection
“The first role of the nervous system, when it comes to movement, is survival and protection,” Grossman says. Muscle tightness might be your nervous system’s way of preventing you from accessing a position it perceives as dangerous. For example, you might not be able to complete a full squat because your body “doesn’t feel strong, stable or in control” in the bottom position.
Habit
If we do anything consistently, the body will adapt to get better at it. Sitting at a desk all day with a flexed hip sends a strong message that this is a position to prioritise. As a result, the nervous system might tighten the hip flexor muscles (which raise the knee towards the chest) to do you a favour and save some energy. Regular, varied movement is the obvious remedy to this – think desk breaks, walking, side bends and rotations (like you’ll find in this three-move ab workout).

Instability
Alternatively, Grossmann says the nervous system can use tightness in the hip flexors as a way of compensating for other muscle’s shortcomings and creating stability in an otherwise unstable joint.
“If the body perceives a joint as loose or unstable, it will tighten the muscles it has to hand or that it’s familiar with to try and create stability, even if they are not the ideal muscles to get the job done,” he explains.
If this is the case, your first course of action should be to recruit and strengthen other key players such as the glutes, adductors and glute medius. You might do this through traditional strength training, or any number of other methods. As Grossmann says: “Anything that gets length and load through the tissues [around the hip] will help.”
The exercise below allows you to do just that, as well as work the hip through a wide range of motion, making it a top option for most people suffering from hip stiffness.

The best exercise for fixing stiff hips: The Stimulus Six Lunges
Grossmann demonstrating the Stimulus Six Lunges
The body operates on a use it or lose it basis, as far as movement is concerned. To persuade it to regain range of motion around the hips and banish tightness, we need to build a solid business case for doing so, says Grossmann.
“The body is pretty rational, so unless you give it a compelling case to say, ‘Actually, we need length through our hip flexors quite often and for reasonable amounts of time’, it won’t buy into it.”

Doing the Stimulus Six Lunges daily is a good way to go about this. It involves lunging in six different directions, recruiting all the main musculature of the hip and moving in all three planes of motion; sagittal, meaning up, down, forward and backward; frontal, meaning side-to-side; and transverse, meaning rotational.
Doing this acts like a mini movement assessment in itself, as you can work out your weaknesses by observing which lunges you struggle with.
“If you don’t like doing a side lunge, maybe the adductors are super tight,” he explains. “If you don’t like doing a crossover lunge, maybe the lateral hip or the glute medius is really tight,” Grossmann says.
“By regularly training those movements, we’re telling the body, ‘We’re going to be doing these movements, so you’d better get used to getting length in these muscles’.”
Done daily, this will help the hips of your average desk job worker feel “way, way better”, he says.

“There’s obviously a lot more nuance you could dig into on an individual basis, but their hips are going to be exposed to more positions and ranges of motion than even a lot of people who go to the gym all the time,” Grossmann explains.
“A lot of gym rats will just do squats and deadlifts, only moving up and down, but not moving sideways or rotating. If you do the Stimulus Six Lunges, you are maintaining your body’s ability to access all the joint motions of the hip.”
If you simply want to maintain your mobility, doing the sequence daily will help. If you’re looking to improve your body’s strength and performance in these positions for sport, you can progressively overload them by adding weight, upping the number of reps or increasing the range of motion accessed in each direction.
“If you can only do a side lunge to 90cm at first, gradually working towards a wider side lunge is another way to track and improve, beyond adding weight,” says Grossmann. “Whether you need to do this all comes back to what your goals are. Do you need more mobility, or are you just trying to keep those hips feeling good and not lose access to those joint positions?”
Ultimately the best thing you can do is listen to your body but if you’re struggling with tightness, it could be worth asking yourself why the feeling keeps returning and look to Grossmann’s advice for help. By taking a slightly different approach you might start to see changes and hopefully, improvements too.

“Forget living longer, exercise can make life easier right now”—a 72-year-old fitness influencer and marathon runner shares two accessible ways to start moving
Retirement is often a time when people slow down, but in Christine Hobson’s case, she’s speeding up. When her daughter persuaded her to join a running club so she wouldn’t get bored, she had no idea she’d get the fitness bug and run 125 marathons in total, visiting all seven continents.
And the 72-year-old former teacher has plans to run the North Pole marathon in 2027.
Hobson, who believes that exercise is the best anti-aging hack, tells Fit&Well: “I think what makes you old is not doing anything and just being sedentary, sitting around watching TV all the time. I really believe the less you move, the less you’re able to move, so when I retired at almost 61, I decided that my new job was to get fit.

“Aging isn’t just about age—if you make life easier now, the future will look after itself,” she says.
Hobson, who strength trains too, has since become a fitness influencer, amassing over 132,000 followers on Instagram, where she shares workouts and her thoughts on exercise.
“I get loads of messages from people who are scared to exercise because they don’t want to fall over and get injured,” she says. “But getting stronger builds your confidence and means that you can do the things you want without needing help. It’s not about living forever. And it’s never too late to start. You’ve got to start from where you are.”
Here shares her two best tips for getting started with fitness, whatever your age.
Start your week with achievable workout ideas, health tips and wellbeing advice in your inbox.
1. Perform the sit-to-stand exercise
Hobson says an essential exercise to incorporate into your day is the sit-to-stand—a move that involves sitting and standing up from a chair without using your hands.
To build your strength, Hobson suggests doing the sit-to-stand 10 times each time you walk past a chair in your house. Once you’ve got the technique, she recommends trying it from a lower chair or couch to make it more challenging.

“The sit-to-stand is critical,” says Hobson. “If you can do that, that’s the thing that’s going to keep you independent in your own home. Because if you live alone and you can’t get up, then how are you going to look after yourself independently? The next thing will be that you can’t get out of your bed, and then you’re in trouble.”
Hobson began with the sit-to-stand exercise, and has progressed to squat with a 35kg barbell and deadlift 75kg.
Many people think motivation will just appear, says Hobson, but she says: “There’s no such thing as motivation really. It’s discipline. It’s building a habit. You’ve got to book your workouts in like a meeting at work, which is what I did when I retired. I prioritized fitness like a job.
“I also have my workout clothes ready to make sure I exercise—even if I’m planning to do it later in the day. I get dressed so I can’t talk myself out of it.”

2. Walk a mile a day
If you’re totally new to exercise, or returning after a long break, Hobson says walking is an excellent place to start.
“We are a species that is supposed to move, and even a short 20-minute walk will support your heart, your ability to control your blood sugar levels, and help you mentally and physically,” she says.
Her trick is to listen to audiobooks while she walks to encourage her to go further.
“This is how I started before I ran my first marathon,” she says. “I walked a mile a day and I really forced myself to do it come rain or shine. After about five or six weeks I found that I wanted to go more.
“And one of the things that helped was listening to audiobooks. If I got home and I had got to an exciting bit in the book I would have to go back out again to hear the next chapter so it would make me walk a bit further.”

Hobson describes herself as a run-walker, saying she has completed all her marathons that way. “I started exercising for something to do when I retired. Now I do it because it makes life easier.”
CrossFit means a lot of things to a lot of people – because it’s made up of a lot of things.
Since the rise of the fitness giant, countless brands, events and training methods have sprung up around it – not claiming to be CrossFit, but looking suspiciously CrossFit-esque.
There are, however, a handful of things that are uniquely CrossFit: the ‘Girls’ benchmark workouts. The Hero WODs and, of course, its signature rep schemes.
Chief among them is ’21-15-9′.
The 21-15-9 rep scheme may just be the single most CrossFit thing in existence. But what exactly is it? Where did it come from? And why might it actually be better at building muscle in a hurry than its conditioning roots would have you believe?
Advertisement
Let’s have a look.
What Is 21-15-9?
If you’ve never encountered it before, the format couldn’t be simpler. Choose two exercises (occasionally more) and perform 21 reps of each, then 15 reps of each, then nine reps of each, completing the entire workout as quickly as possible – with good form.
Probably the best-known example is ‘Fran’: 21 thrusters and pull-ups, followed by 15 of each, then nine. On paper it doesn’t look especially intimidating. In practice, it’s one of the most feared benchmark workouts in fitness.
Where Did it Come From?
Unlike many modern training methods, 21-15-9 didn’t come out of a study. It came from the gym floor.
CrossFit founder Greg Glassman has explained that the format emerged through years of coaching and experimentation in the 1990s. Rather than chasing a perfect sets-and-reps prescription, he was looking for a workout that allowed athletes to maintain a high power output from start to finish.

The thinking is surprisingly elegant. You begin with 21 reps while fresh. By the time you reach the set of 15, your ability to produce force has already fallen. By the final nine, you’re significantly more fatigued – but the workload has dropped by almost the same amount.
Instead of grinding through increasingly miserable sets of the same length, the workout ‘meets you where you are’, reducing the work required as your capacity declines. The result is a workout that encourages you to keep moving instead of standing around trying to recover.
The numbers themselves are also remarkably practical. Forty-five total reps per movement provides plenty of training volume without turning the session into an endurance slog, while every set divides neatly into thirds if you need to break it up.
(Although I’ve got to be honest, I’m a 20-15-10-5 man myself, just for the sake of round numbers.)
Why Does it Work So Well?
Although there isn’t research showing that 21-15-9 is somehow the magic formula, there are obvious reasons why it consistently produces brutally effective workouts.

Descending reps help maintain intensity. As fatigue accumulates, reducing the target allows movement quality, bar speed and overall work rate to stay higher than they would if you simply repeated the same number of reps over and over.
It also tends to land in a physiological sweet spot. Most 21-15-9 workouts take between three and eight minutes, depending on the movements and the athlete. That’s long enough to create a serious cardiovascular challenge while still requiring meaningful force production throughout. You’re taxing your anaerobic systems hard while relying on your aerobic system to help you recover just enough to keep going.
Finally, there’s the psychological trick. The hardest-looking part comes first. Once you’ve survived the opening 21, every remaining round appears more manageable. ‘Only 15 left.’ Then, ‘Just nine.’ In reality, you’re becoming more fatigued with every rep, but the shrinking target keeps you attacking the workout instead of pacing too conservatively.
Why it Might be Surprisingly Good for Building Muscle
Perhaps the biggest misconception about 21-15-9 is that it’s ‘just cardio with weights’.
Choose the right load and something interesting happens. Very few athletes complete every round unbroken. Instead, the workout naturally evolves into a series of short, broken sets separated by only a few seconds of rest.

Your 21 might become 11-5-5. Your 15 becomes 8-4-3. Your final nine might stay unbroken – or become 5-4.
In effect, you’ve accidentally turned the workout into a form of rest-pause training.
Those brief pauses allow just enough recovery to squeeze out more high-quality repetitions before fatigue catches up again. By the latter stages of each mini-set, you’re repeatedly working very close to failure, recruiting the high-threshold motor units with the greatest potential for muscle growth.
It’s a similar principle to rest-pause training, myo-reps and cluster sets: all methods used to accumulate hypertrophy-friendly volume while keeping the load relatively heavy and the rest periods brutally short.
You’re basically speed-running a large number of hard, growth-stimulating reps in a very small window of time. Could this help explain why elite CrossFit athletes often carry an impressive amount of muscle despite spending relatively little time performing traditional bodybuilding splits?

It’s certainly plausible, although the ‘elite’ part often selects for athletes with the greatest muscle-building potential.
Much of their training isn’t simply conditioning. It’s high-density resistance training performed under accumulating fatigue, with only fleeting recovery between efforts. In other words, they’re often doing something bodybuilders have deliberately programmed for decades: packing a lot of hard work into a very short period of time.
That’s not to say 21-15-9 is superior to a well-designed hypertrophy programme. If your sole goal is building muscle, there are more efficient ways to do it.
But if you’re looking for a workout that develops fitness, tests your mettle and still provides a meaningful stimulus for strength and size, it’s easy to see why this deceptively simple rep scheme has remained one of CrossFit’s defining fingerprints for more than 20 years.
Best Bodyweight 21-15-9 Workout: ‘JT’
If you’re looking for an interesting twist on the 21-15-9 format, look no further than Hero WOD ‘JT’, which concentrates the muscle-building potential of the format into a brutal upper-body workout.

Created in honour of Petty Officer 1st Class Jeff Taylor, who was killed in Afghanistan in 2006, the workout strips away barbells altogether and relies solely on three bodyweight movements:
21-15-9 reps of:
Don’t let the lack of equipment fool you. The volume – 45 reps of each movement, 135 reps in total – combined with the descending rep scheme makes this a brutal upper-body test, hammering the shoulders, chest and triceps while demanding serious muscular endurance.
Better still, it perfectly demonstrates one of the biggest strengths of 21-15-9. As fatigue mounts and the sets naturally fragment, the workout begins to resemble one giant rest-pause set, allowing you to accumulate a huge number of hard, near-failure reps in less than 10 minutes.
If your goal is building an impressive upper body while developing serious work capacity, there are few bodyweight workouts that deliver quite so much bang for your buck, making ‘JT’ one of my personal favourites.

The concept of ‘exercise snacking’ has never been more popular. Not only is it convenient and accessible, but there is solid scientific evidence that short bursts of physical activity can yield real benefits for our health. But can a swimming workout be an effective ‘exercise snack’?
A study published in the European Heart Journal found that just 15 to 20 minutes of vigorous physical activity a week (almost as low as two minutes a day) was enough to significantly lower the risk of heart disease, cancer and early death. The study defined vigorous activity as any exercise that leaves you out of breath and raises your heart rate, including swimming.
But does ‘exercise snacking’ really work in the pool? Unlike a short run, walk, or online workout at home, going for a swim requires a bit of effort beyond the swim itself, so we often want to spend longer in the pool to make the most of it. However, head of swim for David Lloyd Clubs, Nuala Muir-Cochrane, believes short swims are worth it: “If you only have 10 minutes, consistency matters more than volume. Even two or three short swims per week can improve swim fitness noticeably,” she says.
With that in mind, I added some 10-minute swims to my routine of strength training and yoga workouts for two weeks to see if it made any difference to my health and fitness. Here’s what I discovered, plus what experts told me about optimising a short swim to either energise, recover or relax.
Benefits of 10-minute swimming workouts
1. Aids muscle recovery
To make the most of my short pool sessions, I often paired them with a gym visit, realising that I’ll need a post-workout shower anyway, so I may as well take a dip first. According to Francesca Bagshaw, performance physiologist at Nuffield Health’s Manchester Institute of Health and Performance, a short swim is perfect for recovering after the gym, a run or exercise class because it combines low-impact movement with increased circulation.

“After a hard session, muscles can feel stiff and fatigued due to microscopic muscle damage, inflammation and metabolite build-up,” she explains. “Gentle swimming helps stimulate blood flow without placing additional mechanical stress on joints and muscles,” Francesca recommends keeping the intensity low to moderate if recovery is your goal, to promote mobility, relaxation and circulation, without additional fatigue.
Samantha Russo, master swim coach for Virgin Active, adds, “In the pool, the water holds most of your bodyweight, so your joints get a break, but your muscles are still working gently through a big range of motion. Because water gives soft resistance in every direction, an easy swim is like active stretching with a built-in massage for the muscles, so you loosen up rather than lock up.”

2. Supports muscle building
Water is around 800 times denser than air, making swimming (or any movement in water) an effective resistance workout. Your muscles need to work harder to propel the body through the water, and multiple muscle groups will be involved, including those in your arms, legs, back and core.

My fortnight of short swims probably didn’t help me gain muscle – the resistance of the water never changes, so practising progressive overload (gradually increasing the weight, as I can in the gym) isn’t possible. I would have to either increase my speed, distance or duration to do this. But I felt that my short swims did support gains from strength training in the gym. Maintaining muscle has been useful for staying strong, not just for my gym workouts, but also for my yoga classes and occasional run.
10 minutes might not seem like a long time, but if you’re headed for the shower anyway, why not throw in a quick workout?

3. Boosts energy levels
While it isn’t my preferred timeslot, I would sometimes schedule a short, pacier swim in the morning to boost my mental and physical energy before work. If you prefer morning workouts, you might find that adding a short, fast swim after the gym or an exercise class will energise you for the day ahead.

Samantha is a fan of morning swims: “In the morning, your circulation and nervous system are still in ‘low power mode’, and a short swim acts like a full-body wake-up call,” she says. “The cold water stimulates your skin and nerves, your breathing and heart rate increase, and more oxygen-rich blood is pushed to your brain and muscles. That mix of oxygen, movement and endorphins clears brain fog and lifts your mood far better than a cup of coffee.”
Francesca adds, “For best results, morning swims should be kept relatively short and refreshing rather than exhaustive, particularly before work or further training later in the day.”
4. Lowers stress levels
Much has been discovered about the effects of immersion in water, and how it can induce an ultra-calming ‘blue mind’state. This is partly why I favour an evening swim, not just to avoid the busiest times at the pool, but to lower my cortisol levels and put a full stop to the day. This can have a calming effect on the nervous system, explains Francesca.
“Steady, rhythmic swimming encourages controlled breathing patterns and can help shift the body toward a more parasympathetic, ‘rest and digest’, state. This reduces physiological arousal and can lower stress levels after a busy day,” she says.

“Warm or temperate water can reduce muscle tension and promote peripheral vasodilation [widening of the blood vessels], helping the body feel physically calmer. The repetitive nature of swimming has a meditative effect for many people, supporting mental decompression and reduced cognitive stress.”
Samantha adds that some may find evening swims contribute to a better night’s sleep: “Your core body temperature rises slightly in the water, then drops as you shower and dry off, and that drop is a natural signal to your brain that it’s time for bed.”
5. Burns calories
The number of calories you burn during a swim will depend on various factors, including the duration, distance, intensity and your bodyweight. For example, according to Harvard Medical School data, someone who weighs 155lb could expect to burn approximately 200 calories over a 30-minute low-intensity swim, rising to 360 calories for a high-intensity 30-minute swim.
Just 10 minutes of swimming will amount to a third of that calorie burn, but the ‘afterburn’ – or excess post-exercise oxygen consumption (EPOC) – may help burn a few more. The ‘afterburn’ concept suggests that we consume more oxygen to help our bodies restore and repair following intense exercise, essentially burning calories at a greater rate. However, research suggests this amounts to just a handful of extra calories burnt.
However, I can be confident that spending an extra 10 minutes swimming in the evening burns more calories than my alternative (usually sitting on the sofa watching TV). It’s the same for a 10-minute walking workout.

10-minute swimming workouts to try
Multi-stroke sprint swimming workout
Nuala recommends this swim workout for beginner-intermediate level swimmers. “It improves cardiovascular fitness without the need for a long session, while using different muscle groups through the stroke changes. The easy swim at the end helps recovery and reduces stiffness,” she says.
How to do it:
For the first five minutes, alternate between front crawl, breaststroke and backstroke for one length each.
On every fourth length, sprint at your near maximum effort. Maintain controlled technique even when swimming faster.
For the final five minutes, cool down with gentle continuous swimming with whichever stroke feels most relaxed. Focus on long strokes with steady breathing and low effort.
Maintaining form is crucial, says Nuala: “For front crawl, keep your head still and look slightly downward rather than forwards; in breaststroke, glide briefly after each kick rather than rushing the strokes; and for backstroke, keep your hips high and do small continuous kicks.”
Varied swimming workout
Cheryl Pottinger, swim teacher for Better, suggests this 10 minute routine which goes up and down the speed scale over 300m (in a standard 25m pool).
How to do it:
Warm up with one length of front crawl, followed by one length of breaststroke at normal pace.
For your main set, swim front crawl with a 10 second rest after each practice, starting with one length at your maximum speed.
Follow it with two lengths at 80% of your maximum speed.
Shift down a gear for the next three lengths at normal pace.
Swim the next two lengths at 80% of your maximum speed.
Finish this section with one length at maximum speed.
Cool down with one length in a stroke of your choice at normal pace.
Recovery swim
As a gentle short swim to aid relaxation after a gym session, Cheryl recommends this sequence. It incorporates the lesser known side stroke, which is relaxed, energy efficient and builds core stability as it forces your midsection to engage as you balance on one side.
How to do it:

Warm up with one length of front crawl and one length of breaststroke at a relaxed pace.
Swim the next two lengths in side stroke, one length on the right side and one on the left. This stroke requires balancing on one side of the body, reaching forward with one arm while the other pulls back, and scissor kicking the legs. “Focus on the power in the muscles during the pull and kick, and the stretching of the muscles during the glide,” says Cheryl. Watch a demo here.
Finish with one length of steady-paced breaststroke, and a final length of head-first sculling (lie on your back using your arms to propel you backwards).
Tips for making the most of a 10-minute swimming workout
Make it your post-gym habit: All the effort involved in travelling to and from the pool, let alone changing in and out of clothes, may not feel worth it for just 10 minutes in the pool. So, I often tacked it onto the end of my regular gym session. If your gym has a pool, make the most of it and view it as part of your workout ‘cool down’ and recovery before showering and heading home.
Tailor your swim to the time of day: There are still benefits to be had if you take a relaxing swim in the morning, or a higher intensity swim in the evening, but you might be working against your energy levels. As Francesca recommends, a pacier swim early in the day can boost alertness, while a lighter intensity swim in the evening can aid post-workout recovery and sleep.
Choose quieter pool times: This goes for however long you wish to spend swimming, but having a lane all to yourself allows you to follow a plan without compromise. I find evenings are best for me but check your local pool timetable to avoid sharing space with unexpected aqua aerobic classes or school swimming lessons.
Bring a poolside kit bag: With just 10 minutes in the pool, you don’t have time to keep nipping back to your locker to fetch forgotten kit. Have a small kit bag pre-packed with anything you might need (think spare hairclips and hairbands, anti-fog goggle spray, kickboard and pull buoy if you’re using them), and keep it at the end of your lane (make sure it isn’t a trip hazard).
